DETAILED DESCRIPTION

Vasopressin and Peptides of the Invention.

Vasopressin, a peptide hormone, acts to regulate water retention in the body and is a neurotransmitter that controls circadian rhythm, thermoregulation, and adrenocorticotrophic hormone (ACTH) release. Vasopressin is synthesized as a pro-hormone in neurosecretory cells of the hypothalamus, and is subsequently transported to the pituitary gland for storage. Vasopressin is released upon detection of hyperosmolality in the plasma, which can be due to dehydration of the body. Upon release, vasopressin increases the permeability of collecting ducts in the kidney to reduce renal excretion of water. The decrease in renal excretion of water leads to an increase in water retention of the body and an increase in blood volume. At higher concentrations, vasopressin raises blood pressure by inducing vasoconstriction.

Vasopressin acts through various receptors in the body including, for example, the V1, V2, V3, and oxytocin-type (OTR) receptors. The V1 receptors occur on vascular smooth muscle cells, and the major effect of vasopressin action on the V1 receptor is the induction of vasoconstriction via an increase of intracellular calcium. V2 receptors occur on the collecting ducts and the distal tubule of the kidney. V2 receptors play a role in detection of plasma volume and osmolality. V3 receptors occur in the pituitary gland and can cause ACTH release upon vasopressin binding. OTRs can be found on the myometrium and vascular smooth muscle. Engagement of OTRs via vasopressin leads to an increase of intracellular calcium and vasoconstriction.

Vasopressin is a nonapeptide, illustrated below (SEQ ID NO. 1):

At neutral to acidic pH, the two basic groups of vasopressin, the N-terminal cysteine, and the arginine at position eight, are protonated, and can each carry an acetate counterion. The amide groups of the N-terminal glycine, the glutamine at position four, and the asparagine at position five, are susceptible to modification when stored as clinical formulations, such as unit dosage forms. The glycine, glutamine, and asparagine residues can undergo deamidation to yield the parent carboxylic acid and several degradation products as detailed in EXAMPLE 1 and TABLE 1 below.

Deamidation is a peptide modification during which an amide group is removed from an amino acid, and can be associated with protein degradation, apoptosis, and other regulatory functions within the cell. Deamidation of asparagine and glutamine residues can occur in vitro and in vivo, and can lead to perturbation of the structure and function of the affected proteins. The susceptibility to deamidation can depend on primary sequence of the protein, three-dimensional structure of the protein, and solution properties including, for example, pH, temperature, ionic strength, and buffer ions. Deamidation can be catalyzed by acidic conditions. Under physiological conditions, deamidation of asparagine occurs via the formation of a five-membered succinimide ring intermediate by a nucleophilic attack of the nitrogen atom in the following peptide bond on the carbonyl group of the asparagine side chain. Acetylation is a peptide modification whereby an acetyl group is introduced into an amino acid, such as on the N-terminus of the peptide.

Vasopressin can also form dimers in solution and in vivo. The vasopressin dimers can occur through the formation of disulfide bridges that bind a pair of vasopressin monomers together. The dimers can form between two parallel or anti-parallel chains of vasopressin.

Vasopressin and associated degradation products or peptides are listed in TABLE 1 below. All amino acids are L-stereoisomers unless otherwise denoted.

A formulation of vasopressin can be used to regulate plasma osmolality and volume and conditions related to the same in a subject. Vasopressin can be used to modulate blood pressure in a subject, and can be indicated in a subject who is hypotensive despite treatment with fluid and catecholamines.

Vasopressin can be used in the treatment of, for example, vasodilatory shock, post-cardiotomy shock, sepsis, septic shock, cranial diabetes insipidus, polyuria, nocturia, polydypsia, bleeding disorders, Von Willebrand disease, haemophilia, platelet disorders, cardiac arrest, liver disease, liver failure, hypovolemia, hemorrhage, oesophageal variceal haemorrhage, hypertension, pulmonary hypertension, renal disease, polycystic kidney disease, blood loss, injury, hypotension, meniere disease, uterine myomas, brain injury, mood disorder. Formulations of vasopressin can be administered to a subject undergoing, for example, surgery or hysterectomy.

Plasma osmolality is a measure of the plasma's electrolyte-water balance and relates to blood volume and hydration of a subject. Normal plasma osmolality in a healthy human subject range from about 275 milliosmoles/kg to about 295 milliosmoles/kg. High plasma osmolality levels can be due to, for example, diabetes insipidus, hyperglycemia, uremia, hypernatremia, stroke, and dehydration. Low plasma osmolality can be due to, for example, vasopressin oversecretion, improper functioning of the adrenal gland, lung cancer, hyponatremia, hypothyroidism, and over-consumption of water or other fluids.

Septic shock can develop due to an extensive immune response following infection and can result in low blood pressure. Causes of sepsis can include, for example, gastrointestinal infections, pneumonia, bronchitis, lower respiratory tract infections, kidney infection, urinary tract infections, reproductive system infections, fungal infections, and viral infections. Risk factors for sepsis include, for example, age, prior illness, major surgery, long-term hospitalization, diabetes, intravenous drug use, cancer, use of steroidal medications, and long-term use of antibiotics. The symptoms of sepsis can include, for example, cool arms and legs, pale arms and legs, extreme body temperatures, chills, light-headedness, decreased urination, rapid breathing, edema, confusion, elevated heart rate, high blood sugar, metabolic acidosis, respiratory alkalosis, and low blood pressure.

Vasopressin can also be administered to regulate blood pressure in a subject. Blood pressure is the measure of force of blood pushing against blood vessel walls. Blood pressure is regulated by the nervous and endocrine systems and can be used as an indicator of a subject's health. Chronic high blood pressure is referred to as hypertension, and chronic low blood pressure is referred to as hypotension. Both hypertension and hypotension can be harmful if left untreated.

Blood pressure can vary from minute to minute and can follow the circadian rhythm with a predictable pattern over a 24-hour period. Blood pressure is recorded as a ratio of two numbers: systolic pressure (mm Hg), the numerator, is the pressure in the arteries when the heart contracts, and diastolic pressure (mm Hg), the denominator, is the pressure in the arteries between contractions of the heart. Blood pressure can be affected by, for example, age, weight, height, sex, exercise, emotional state, sleep, digestion, time of day, smoking, alcohol consumption, salt consumption, stress, genetics, use of oral contraceptives, and kidney disease.

Blood pressure for a healthy human adult between the ages of 18-65 can range from about 90/60 to about 120/80. Hypertension can be a blood pressure reading above about 120/80 and can be classified as hypertensive crisis when there is a spike in blood pressure and blood pressure readings reach about 180/110 or higher. Hypertensive crisis can be precipitated by, for example, stroke, myocardial infarction, heart failure, kidney failure, aortic rupture, drug-drug interactions, and eclampsia. Symptoms of hypertensive crisis can include, for example, shortness of breath, angina, back pain, numbness, weakness, dizziness, confusion, change in vision, nausea, and difficulty speaking.

Vasodilatory shock can be characterized by low arterial blood pressure due to decreased systemic vascular resistance. Vasodilatory shock can lead to dangerously low blood pressure levels and can be corrected via administration of catecholamines or vasopressin formulations. Vasodilatory shock can be caused by, for example, sepsis, nitrogen intoxication, carbon monoxide intoxication, hemorrhagic shock, hypovolemia, heart failure, cyanide poisoning, metformin intoxication, and mitochondrial disease.

Post-cardiotomy shock can occur as a complication of cardiac surgery and can be characterized by, for example, inability to wean from cardiopulmonary bypass, poor hemodynamics in the operating room, development of poor hemodynamics post-surgery, and hypotension.

Non-limiting examples of methods that can be used to identify peptides of the invention include high-performance liquid chromatography (HPLC), mass spectrometry (MS), Matrix Assisted Laser Desorption Ionization Time-of-Flight (MALDI-TOF), electrospray ionization Time-of-flight (ESI-TOF), gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and two-dimensional gel electrophoresis.

HPLC can be used to identify peptides using high pressure to separate components of a mixture through a packed column of solid adsorbent material, denoted the stationary phase. The sample components can interact differently with the column based upon the pressure applied to the column, material used in stationary phase, size of particles used in the stationary phase, the composition of the solvent used in the column, and the temperature of the column. The interaction between the sample components and the stationary phase can affect the time required for a component of the sample to move through the column. The time required for component to travel through the column from injection point to elution is known as the retention time.

Upon elution from the column, the eluted component can be detected using a UV detector attached to the column. The wavelength of light at which the component is detected, in combination with the component's retention time, can be used to identify the component. Further, the peak displayed by the detector can be used to determine the quantity of the component present in the initial sample. Wavelengths of light that can be used to detect sample components include, for example, about 200 nM, about 225 nm, about 250 nm, about 275 nm, about 300 nm, about 325 nm, about 350 nm, about 375 nm, and about 400 nm.

Mass spectrometry (MS) can also be used to identify peptides of the invention. To prepare samples for MS analysis, the samples, containing the proteins of interest, are digested by proteolytic enzymes into smaller peptides. The enzymes used for cleavage can be, for example, trypsin, chymotrypsin, glutamyl endopeptidase, Lys-C, and pepsin. The samples can be injected into a mass spectrometer. Upon injection, all or most of the peptides can be ionized and detected as ions on a spectrum according to the mass to charge ratio created upon ionization. The mass to charge ratio can then be used to determine the amino acid residues present in the sample.

EXAMPLES Example 1: Impurities of Vasopressin as Detected by HPLC

To analyze degradation products of vasopressin that can be present in an illustrative formulation of vasopressin, gradient HPLC was performed to separate vasopressin from related peptides and formulation components. TABLE 2 below depicts the results of the experiment detailing the chemical formula, relative retention time (RRT), molar mass, and structure of vasopressin and detected impurities.

Vasopressin was detected in the eluent using UV absorbance. The concentration of vasopressin in the sample was determined by the external standard method, where the peak area of vasopressin in sample injections was compared to the peak area of vasopressin reference standards in a solution of known concentration. The concentrations of related peptide impurities in the sample were also determined using the external standard method, using the vasopressin reference standard peak area and a unit relative response factor. An impurities marker solution was used to determine the relative retention times of identified related peptides at the time of analysis.

Experimental conditions are summarized in TABLE 2 below.

TABLE 2 Column YMC-Pack ODS-AM, 3 μm, 120 Å pore, 4.6 × 100 mm Column Temperature 25° C. Flow Rate 1.0 mL/min Detector 215 nm Note: For Identification a Diode Array Detector (DAD) was used with the range of 200-400 nm. Injection Volume 100 μL Run time 55 minutes Autosampler Vials Polypropylene vials Pump (gradient) Time (min) % A % B Flow  0 90 10 1.0 40 50 50 1.0 45 50 50 1.0 46 90 10 1.0 55 90 10 1.0

The diluent used for the present experiment was 0.25% v/v Acetic Acid, which was prepared by transferring 2.5 mL of glacial acetic acid into a 1-L volumetric flask containing 500 mL of water. The solution was diluted to the desired volume with water.

Phosphate buffer at pH 3.0 was used for mobile phase A. The buffer was prepared by weighing approximately 15.6 g of sodium phosphate monobasic monohydrate into a beaker. 1000 mL of water was added, and mixed well. The pH was adjusted to 3.0 with phosphoric acid. The buffer was filtered through a 0.45 μm membrane filter under vacuum, and the volume was adjusted as necessary.

An acetonitrile:water (50:50) solution was used for mobile phase B. To prepare mobile phase B, 500 mL of acetonitrile was mixed with 500 mL of water.

The working standard solution contained approximately 20 units/mL of vasopressin. The standard solution was prepared by quantitatively transferring the entire contents of 1 vial of USP Vasopressin RS with diluent to a 50-mL volumetric flask.

The intermediate standard solution was prepared by pipetting 0.5 mL of the working standard solution into a 50-mL volumetric flask.

The sensitivity solution was prepared by pipetting 5.0 mL of the intermediate standard solution into a 50-mL volumetric flask. The solution was diluted to the volume with Diluent and mixed well.

A second working standard solution was prepared as directed under the standard preparation.

A portion of the vasopressin control sample was transferred to an HPLC vial and injected. The control was stable for 120 hours when stored in autosampler vials at ambient laboratory conditions.

To prepare the impurities marker solution, a 0.05% v/v acetic acid solution was prepared by pipetting 200.0 mL of a 0.25% v/v acetic acid solution into a 1-L volumetric flask. The solution was diluted to the desired volume with water and mixed well.

To prepare the vasopressin impurity stock solutions, the a solution of each impurity was prepared in a 25 mL volumetric flask and diluted with 0.05% v/v acetic acid to a concentration suitable for HPLC injection.

To prepare the MAA/H-IBA (Methacrylic Acid/α-Hydroxy-isobutyric acid) stock solution, a stock solution containing approximately 0.3 mg/mL H-IBA and 0.01 mg/mL in 0.05% v/v acetic acid was made in a 50 mL volumetric flask.

To prepare the chlorobutanol diluent, about one gram of hydrous chlorobutanol was added to 500 mL of water. Subsequently, 0.25 mL of acetic acid was added and the solution was stirred to dissolve the chlorobutanol.

To prepare the impurity marker solution, vasopressin powder was mixed with the impurity stock solutions prepared above.

The solutions were diluted to volume with the chlorobutanol diluent. The solutions were aliquoted into individual crimp top vials and stored at 2-8° C. At time of use, the solutions were removed from refrigeration (2-8° C.) and allowed to reach room temperature.

The vasopressin impurity marker solution was stable for at least 120 hours when stored in auto-sampler vials at ambient laboratory conditions. The solution was suitable for use as long as the chromatographic peaks could be identified based on comparison to the reference chromatogram.

To begin the analysis, the HPLC system was allowed to equilibrate for at least 30 minutes using mobile phase B, followed by time 0 min gradient conditions until a stable baseline was achieved.

The diluent was injected at the beginning of the run, and had no peaks that interfered with Vasopressin at around 18 minutes as shown in FIG. 1.

A single injection of the sensitivity solution was performed, wherein the signal-to-noise ratio of the Vasopressin was greater than or equal to ten as shown in FIG. 2.

A single injection of the impurities marker solution was then made. The labeled impurities in the reference chromatogram were identified in the chromatogram of the marker solution based on their elution order and approximate retention times shown in FIG. 3 and FIG. 4. FIG. 4 is a zoomed in chromatograph of FIG. 3 showing the peaks that eluted between 15 and 30 minutes. The nomenclature, structure, and approximate retention times for individual identified impurities are detailed in TABLE 3.

A single injection of the working standard solution was made to ensure that the tailing factor of the vasopressin peak was less than or equal to about 2.0 as shown in FIG. 5.

A total of five replicate injections of the working standard solution were made to ensure that the relative standard deviation (% RSD) of the five replicate vasopressin peak areas was not more than 2.0%.

Two replicate injections of the check standard preparation were to confirm that the check standard conformity was 99.0%-101.0%. One injection of the control sample was made to confirm that the assay of the control sample met the control limits established for the sample.

Then, one injection of the working standard solution was made.

Following the steps above done to confirm system suitability, a single injection of each sample preparation was made. The chromatograms were analyzed to determine the vasopressin and impurity peak areas. The chromatogram is depicted in FIG. 6.

The working standard solution was injected after 1 to 4 sample injections, and the bracketing standard peak areas were averaged for use in the calculations to determine peak areas of vasopressin and associated impurities.

The relative standard deviation (% RSD) of vasopressin peak areas for the six injections of working standard solution was calculated by including the initial five injections from the system suitability steps above and each of the subsequent interspersed working standard solution injections. The calculations were done to ensure that each of the % RSD were not more than 2.0%.

The retention time of the major peak in the chromatogram of the sample preparation corresponded to that of the vasopressin peak in the working standard solution injection that preceded the sample preparation injection.

The UV spectrum (200-400 nm) of the main peak in the chromatogram of the sample preparation compared to the UV spectrum of vasopressin in the working standard preparation. FIG. 7 depicts a UV spectrum of a vasopressin sample and FIG. 8 depicts a UV spectrum of vasopressin standard.

To calculate the vasopressin units/mL, the following formula was used:

${{Vasopressin}\mspace{14mu}{units}\text{/}{mL}} = {\frac{R_{U}}{R_{S}} \times {Conc}\mspace{14mu}{STD}}$

where:

R_(U)=Vasopressin peak area response of Sample preparation.

R_(S)=average vasopressin peak area response of bracketing standards.

Conc STD=concentration of the vasopressin standard in units/mL

To identify the impurities, the % Impurity and identity for identified impurities (TABLE 3) that are were greater than or equal to 0.10% were reported. Impurities were truncated to 3 decimal places and then rounded to 2 decimal places, unless otherwise specified.

The impurities were calculated using the formula below:

${\%\mspace{14mu}{impurity}} = {\frac{R_{I}}{R_{S}} \times \frac{{Conc}\mspace{14mu}{STD}}{20\mspace{14mu} U\text{/}{mL}} \times 100\%}$

where:

R_(I)=Peak area response for the impurity

20 U/mL=Label content of vasopressin

TABLE 3 below details the chemical formula, relative retention time (RRT in minutes), molar mass, and structure of vasopressin and detected impurities.

Example 2: Investigation of pH

To determine a possible pH for a vasopressin formulation with good shelf life, vasopressin formulations were prepared in 10 mM citrate buffer diluted in isotonic saline across a range of pH. Stability was assessed via HPLC as in EXAMPLE 1 after incubation of the formulations at 60° C. for one week. FIG. 9 illustrates the results of the experiment. The greatest level of stability was observed at pH 3.5. At pH 3.5, the percent label claim (% LC) of vasopressin was highest, and the proportion of total impurities was lowest.

Example 3: Effect of Peptide Stabilizers on Vasopressin Formulation

To observe the effect of stabilizers on the degradation of vasopressin, a series of peptide stabilizers were added to a vasopressin formulation as detailed in TABLE 4. Stability of vasopressin was assessed via HPLC after incubation of the formulations at 60° C. for one week.

TABLE 4 PEG Poloxamer n-Methylpyrrolidone Ethanol 400 Glycerol 188 HPbCD^(a) (NMP)  1%  1%  1%  1%  1%  1% 10% 10% 10% 10% 10% 10% ^(a)Hydroxypropyl beta-Cyclodextrin

FIG. 10 illustrates the stability of vasopressin in terms of % label claim at varying concentrations of stabilizer. The results indicate that the tested stabilizers provided a greater stabilizing effect at 1% concentration than at 10%. Also, in several cases the stabilization effect was about 5% to about 10% greater than that observed in the experiments of EXAMPLE 2.

Example 4: Effect of Buffer and Divalent Metals on Vasopressin Formulation

To determine whether different combinations of buffers and use of divalent metals affect vasopressin stability, vasopressin formulations with varying concentrations of citrate and acetate buffers and variable concentrations of calcium, magnesium, and zinc ions were prepared. Solutions of 0 mM, 10 mM, 20 mM, and 80 mM calcium, magnesium, and zinc were prepared and each was combined with 1 mM or 10 mM of citrate or acetate buffers to test vasopressin stability.

The tested combinations provided vasopressin stability comparable to that of a vasopressin formulation lacking buffers and divalent metals. However, that the addition of divalent metal ions was able to counteract the degradation of vasopressin caused by the use of a citrate buffer.

Example 5: Illustrative Formulations for Assessment of Vasopressin Stability

An aqueous formulation of vasopressin is prepared using 10% trehalose, 1% sucrose, or 5% NaCl and incubated at 60° C. for one week, at which point stability of vasopressin is assessed using HPLC.

A formulation containing 50 units of vasopressin is lyophilized. The lyophilate is reconstituted with water and either 100 mg of sucrose or 100 mg of lactose, and the stability of vasopressin is tested via HPLC after incubation at 60° C. for one week.

Co-solvents are added to a vasopressin solution to assess vasopressin stability. 95% solvent/5% 20 mM acetate buffer solutions are prepared using propylene glycol, DMSO, PEG300, NMP, glycerol, and glycerol:NMP (1:1), and used to create formulations of vasopressin. The stability of vasopressin is tested after incubation at 60° C. for one week.

Amino acid and phosphate buffers are tested with vasopressin to assess vasopressin stability. Buffers of 10 mM glycine, aspartate, phosphate are prepared at pH 3.5 and 3.8 and used to create formulations of vasopressin. The stability of vasopressin is tested after incubation at 60° C. for one week.

A vasopressin formulation in 10% polyvinylpyrrolidone is prepared to assess vasopressin stability. The stability of vasopressin will be tested after incubation at 60° C. for one week.

A vasopressin formulation that contains 0.9% saline, 10 mM acetate buffer, 0.2 unit/mL API/mL in 100 mL of total volume is prepared. The pH of the solution is varied from pH 3.5-3.8 to test the stability of vasopressin.

A vasopressin formulation in about 50% to about 80% DMSO (for example, about 80%), about 20% to about 50% ethyl acetate (for example, about 20%), and about 5% to about 30% polyvinylpyrrolidone (PVP) (for example, about 10% by mass of the formulation) is prepared to assess vasopressin stability. PVP K12 and PVP K17 are each independently tested in the formulation. The stability of vasopressin is tested after incubation at 60° C. for one week.

A vasopressin formulation in about 70% to about 95% ethyl acetate, and about 5% to about 30% PVP is prepared to assess vasopressin stability. PVP K12 and PVP K17 are each independently tested in the formulation. The stability of vasopressin is tested after incubation at 60° C. for one week.

Example 6: Illustrative Vasopressin Formulation for Clinical Use

A formulation for vasopressin that can be used in the clinic is detailed in TABLE 5 below:

TABLE 5 Ingredient Function Amount (per mL) Vasopressin, USP Active Ingredient 20 Units (~0.04 mg) Chlorobutanol, Hydrous NF Preservative 5.0 mg Acetic Acid, NF pH Adjustment To pH 3.4-3.6 (~0.22 mg) Water for injection, USP/EP Diluent QS

Example 7: Illustrative Regimen for Therapeutic Use of a Vasopressin Formulation

Vasopressin is indicated to increase blood pressure in adults with vasodilatory shock (for example, adults who are post-cardiotomy or septic) who remain hypotensive despite fluids and catecholamines.

Preparation and Use of Vasopressin.

Vasopressin is supplied in a carton of 25 multi-dose vials each containing 1 mL vasopressin at 20 units/mL.

Vasopressin is stored between 15° C. and 25° C. (59° F. and 77° F.), and is not frozen. Alternatively, a unit dosage form of vasopressin can be stored between 2° C. and 8° C. for about 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, or 8 weeks.

Vials of vasopressin are to be discarded 48 hours after first puncture.

Vasopressin is prepared according to TABLE 6 below:

TABLE 6 Mix Fluid Restriction? Final Concentration Vasopressin Diluent No 0.1 units/mL 2.5 mL (50 units) 500 mL Yes 1 unit/mL 5 mL (100 units) 100 mL

Vasopressin is diluted in normal saline (0.9% sodium chloride) or 5% dextrose in water (D5W) prior to use to either 0.1 units/mL or 1 unit/mL for intravenous administration. Unused diluted solution is discarded after 18 hours at room temperature or after 24 hours under refrigeration.

Diluted vasopressin should be inspected for particulate matter and discoloration prior to use whenever solution and container permit.

The goal of treatment with vasopressin is optimization of perfusion to critical organs, but aggressive treatment can compromise perfusion of organs, like the gastrointestinal tract, for which function is difficult to monitor. Titration of vasopressin to the lowest dose compatible with a clinically-acceptable response is recommended.

For post-cardiotomy shock, a dose of 0.03 units/minute is used as a starting point. For septic shock, a dose of 0.01 units/minute is recommended. If the target blood pressure response is not achieved, titrate up by 0.005 units/minute at 10- to 15-minute intervals. The maximum dose for post-cardiotomy shock is 0.1 units/minute and for septic shock 0.07 units/minute. After target blood pressure has been maintained for 8 hours without the use of catecholamines, taper vasopressin by 0.005 units/minute every hour as tolerated to maintain target blood pressure.

Vasopressin is provided at 20 units per mL of diluent, which is packaged as 1 mL of vasopressin per vial, and is diluted prior to administration.

Contraindications, Adverse Reactions, and Drug-Drug Interactions.

Vasopressin is contraindicated in patients with known allergy or hypersensitivity to 8-L-arginine vasopressin or chlorobutanol. Additionally, use of vasopressin in patients with impaired cardiac response can worsen cardiac output.

Adverse reactions have been observed with the use of vasopressin, which adverse reactions include bleeding/lymphatic system disorders, specifically, hemorrhagic shock, decreased platelets, intractable bleeding; cardiac disorders, specifically, right heart failure, atrial fibrillation, bradycardia, myocardial ischemia; gastrointestinal disorders, specifically, mesenteric ischemia; hepatobiliary disorders, specifically, increased bilirubin levels; renal/urinary disorders, specifically, acute renal insufficiency; vascular disorders, specifically, distal limb ischemia; metabolic disorders, specifically, hyponatremia; and skin disorders, specifically, and ischemic lesions.

These reactions are reported voluntarily from a population of uncertain size. Thus, reliable estimation of frequency or establishment of a causal relationship to drug exposure is unlikely.

Vasopressin has been observed to interact with other drugs. For example, use of vasopressin with catecholamines is expected to result in an additive effect on mean arterial blood pressure and other hemodynamic parameters. Use of vasopressin with indomethacin can prolong the effect of vasopressin on cardiac index and systemic vascular resistance. Indomethacin more than doubles the time to offset for vasopressin's effect on peripheral vascular resistance and cardiac output in healthy subjects.

Further, use of vasopressin with ganglionic blocking agents can increase the effect of vasopressin on mean arterial blood pressure. The ganglionic blocking agent tetra-ethylammonium increases the pressor effect of vasopressin by 20% in healthy subjects.

Use of vasopressin with furosemide increases the effect of vasopressin on osmolar clearance and urine flow. Furosemide increases osmolar clearance 4-fold and urine flow 9-fold when co-administered with exogenous vasopressin in healthy subjects.

Use of vasopressin with drugs suspected of causing SIADH (Syndrome of inappropriate antidiuretic hormone secretion), for example, SSRIs, tricyclic antidepressants, haloperidol, chlorpropamide, enalapril, methyldopa, pentamidine, vincristine, cyclophosphamide, ifosfamide, and felbamate can increase the pressor effect in addition to the antidiuretic effect of vasopressin. Additionally, use of vasopressin with drugs suspected of causing diabetes insipidus for example, demeclocycline, lithium, foscarnet, and clozapine can decrease the pressor effect in addition to the antidiuretic effect of vasopressin.

Halothane, morphine, fentanyl, alfentanyl and sufentanyl do not impact exposure to endogenous vasopressin.

Use of Vasopressin in Specific Populations.

Vasopressin is a Category C drug for pregnancy.

Due to a spillover into the blood of placental vasopressinase, the clearance of exogenous and endogenous vasopressin increases gradually over the course of a pregnancy. During the first trimester of pregnancy the clearance is only slightly increased. However, by the third trimester the clearance of vasopressin is increased about 4-fold and at term up to 5-fold. Due to the increased clearance of vasopressin in the second and third trimester, the dose of vasopressin can be up-titrated to doses exceeding 0.1 units/minute in post-cardiotomy shock and 0.07 units/minute in septic shock. Vasopressin can produce tonic uterine contractions that could threaten the continuation of pregnancy. After delivery, the clearance of vasopressin returns to preconception levels.

Overdosage.

Overdosage with vasopressin can be expected to manifest as a consequence of vasoconstriction of various vascular beds, for example, the peripheral, mesenteric, and coronary vascular beds, and as hyponatremia. In addition, overdosage of vasopressin can lead less commonly to ventricular tachyarrhythmias, including Torsade de Pointes, rhabdomyolysis, and non-specific gastrointestinal symptoms. Direct effects of vasopressin overdose can resolve within minutes of withdrawal of treatment.

Pharmacology of Vasopressin.

Vasopressin is a polypeptide hormone that causes contraction of vascular and other smooth muscles and antidiuresis, which can be formulated as a sterile, aqueous solution of synthetic arginine vasopressin for intravenous administration. The 1 mL solution contains vasopressin 20 units/mL, chlorobutanol, NF 0.5% as a preservative, and water for injection, USP adjusted with acetic acid to pH 3.4-3.6.

The chemical name of vasopressin is Cyclo (1-6) L-Cysteinyl-L-Tyrosyl-L-Phenylalanyl-L-Glutaminyl-L-Asparaginyl-L-Cysteinyl-L-Prolyl-L-Arginyl-L-Glycinamide. Vasopressin is a white to off-white amorphous powder, freely soluble in water. The structural formula of vasopressin is:

Molecular Formula: C₄₆H₆₅N₁₅O₁₂S₂; Molecular Weight: 1084.23

One mg of vasopressin is equivalent to 530 units. Alternatively, one mg of vasopressin is equivalent to 470 units.

The vasoconstrictive effects of vasopressin are mediated by vascular V1 receptors. Vascular V1 receptors are directly coupled to phopholipase C, resulting in release of calcium, leading to vasoconstriction. In addition, vasopressin stimulates antidiuresis via stimulation of V2 receptors which are coupled to adenyl cyclase.

At therapeutic doses, exogenous vasopressin elicits a vasoconstrictive effect in most vascular beds including the splanchnic, renal, and cutaneous circulation. In addition, vasopressin at pressor doses triggers contractions of smooth muscles in the gastrointestinal tract mediated by muscular V1-receptors and release of prolactin and ACTH via V3 receptors. At lower concentrations typical for the antidiuretic hormone, vasopressin inhibits water diuresis via renal V2 receptors. In patients with vasodilatory shock, vasopressin in therapeutic doses increases systemic vascular resistance and mean arterial blood pressure and reduces the dose requirements for norepinephrine.

Vasopressin tends to decrease heart rate and cardiac output. The pressor effect is proportional to the infusion rate of exogenous vasopressin. Onset of the pressor effect of vasopressin is rapid, and the peak effect occurs within 15 minutes. After stopping the infusion, the pressor effect fades within 20 minutes. There is no evidence for tachyphylaxis or tolerance to the pressor effect of vasopressin in patients.

At infusion rates used in vasodilatory shock (0.01-0.1 units/minute), the clearance of vasopressin is 9 to 25 mL/min/kg in patients with vasodilatory shock. The apparent half-life of vasopressin at these levels is ≤10 minutes. Vasopressin is predominantly metabolized and only about 6% of the dose is excreted unchanged in urine. Animal experiments suggest that the metabolism of vasopressin is primarily by liver and kidney. Serine protease, carboxipeptidase and disulfide oxido-reductase cleave vasopressin at sites relevant for the pharmacological activity of the hormone. Thus, the generated metabolites are not expected to retain important pharmacological activity.

Carcinogenesis, Mutagenesis, Impairment of Fertility.

Vasopressin was found to be negative in the in vitro bacterial mutagenicity (Ames) test and the in vitro Chinese hamster ovary (CHO) cell chromosome aberration test. In mice, vasopressin can have an effect on function and fertilizing ability of spermatozoa.

Clinical Studies.

Increases in systolic and mean blood pressure following administration of vasopressin were observed in seven studies in septic shock and eight studies in post-cardiotomy vasodilatory shock.

Example 8: Effect of Temperature on Vasopressin Formulations

To test the effect of temperature on the stability of vasopressin formulation, solutions containing 20 units/mL vasopressin and chlorobutanol, adjusted to pH 3.5 with acetic acid, were prepared. One mL of each vasopressin formulations was then filled into 3 cc vials. Each Vasopressin Formulation was stored either inverted or upright for at least three months, up to 24 months, at: (i) 5° C.; (ii) 25° C. and 60% relative humidity; or (iii) 40° C. and 75% humidity, and the amount of vasopressin (U/mL) and % total impurities were measured periodically. TABLES 7-12 below display the results of the experiments at 5° C. The results of the experiments at 25° C. are included in TABLES 13-18. All of the experiments were performed in triplicate. The results of the experiments at 40° C. are included in TABLES 19-24. For each temperature tested, three lots of the vasopressin formulation were stored for 24 months (5° C. and 25° C.) and 3 months (40° C.), and measurements were taken at regular intervals during the testing periods. “NMT” as used in the tables denotes “not more than.”

The vasopressin and impurity amounts observed in the experiments conducted at 5° C. are shown in TABLES 7-12 below (AVP=Vasopressin).

The results of the above experiments suggested that storage in either an upright or inverted position did not markedly affect the stability of vasopressin. The samples held at 5° C. exhibited little fluctuation in vasopressin amounts over 24 months, and the amount of total impurities did not increase above 3% during the testing period (TABLES 7-12). The samples held at 25° C. and 60% relative humidity exhibited a decrease in vasopressin amount of about 10-12% after 24 months (TABLES 13-18). The amount of impurities observed in the samples stored at 25° C. and 60% relative humidity after 24 months exceeded 13% in some samples, whereas the amount of impurities observed in the samples stored at 5° C. did not exceed 3% after 24 months. After about three months, the samples held at 40° C. exhibited a decrease in the amount of vasopressin of about 10-12%. The amount of impurities observed at 40° C. exceeded 10% after three months, whereas the amount of impurities observed in the samples stored at 5° C. was less than 3% after three months (TABLES 19-24).

Experiments were also conducted on the same samples above over the course of the experiments to measure the amount of individual impurities in the samples, pH of the samples, chlorobutanol content, particulate matter, antimicrobial effectiveness, and bacterial endotoxin levels (TABLES 25-42). (NR=no reading; ND=not determined; UI=unidentified impurity).

The anti-microbial effectiveness of the solution was established to determine the amount of antimicrobial agents in the formulation that protect against bacterial contamination. The bullets in the tables below indicate that the sample was not tested for anti-microbial effectiveness at that specific time point.

The bacterial endotoxin levels were also measured for some of the formulations. The bullets in the tables below indicate that the sample was not tested for bacterial endotoxin levels at that specific time point.

Example 9: Effect of pH 3.5-4.5 on Vasopressin Formulations

To test of effect of pH on vasopressin formulations, solutions containing 20 units/mL vasopressin, adjusted to pH 3.5, 3.6, 3.7, 3.8, 3.9, 4, 4.1, 4.2, 4.3, 4.4, or 4.5 with 10 mM acetate buffer, were prepared. One mL of each of the vasopressin formulations was then filled into 10 cc vials.

The vasopressin formulations were stored for four weeks at: (i) 25° C.; or (ii) 40° C., and the assay (% label claim; vasopressin remaining) and % total impurities after four weeks were measured using the methods described in EXAMPLE 1. FIGS. 11 and 12 below display the results of the experiments at 25° C. The results of the experiments at 40° C. are included in FIGS. 13 and 14.

The results of the experiments suggested that the stability of a vasopressin formulation was affected by pH. At 25° C., the remaining vasopressin after four weeks was highest between pH 3.6 and pH 3.8 (FIG. 11). Within the range of pH 3.6 to pH 3.8, the level of impurities was lowest at pH 3.8 (FIG. 12). At 25° C., pH 3.7 provided the highest stability for vasopressin (FIG. 11).

At 40° C., the remaining vasopressin after four weeks was highest between pH 3.6 and pH 3.8 (FIG. 13). Within the range of pH 3.6 to pH 3.8, the level of impurities was lowest at pH 3.8 (FIG. 14). At 40° C., pH 3.6 provided the highest stability for vasopressin (FIG. 13),

Example 10: Effect of pH 2.5-4.5 of Vasopressin Formulations

To test of effect of pH on vasopressin formulations, solutions containing 20 units/mL vasopressin, adjusted to pH 2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, or 3.4 with 10 mM acetate buffer were also prepared. One mL of each of the vasopressin formulations was then filled into 10 cc vials.

The amount of vasopressin, impurities, and associated integration values were determined using the methods describes in EXAMPLE 1. The results from the stability tests on the vasopressin formulations from pH 2.5 to 3.4 were plotted against the results from the stability tests on vasopressin formulations from pH 3.5 to 4.5 as disclosed in EXAMPLE 9, and are displayed in FIGS. 15-18.

The assay (% label claim; vasopressin remaining) and % total impurities in the vasopressin pH 2.5 to 3.4 formulations after four weeks are reported in TABLE 43.

The % total impurities for the pH 2.5 to 3.4 formulations and the pH 3.5 to 4.5 formulations observed in the experiments conducted at 25° C. and 40° C. are shown in FIGS. 15 (25° C.) and 16 (40° C.).

The vasopressin assay amount for the vasopressin pH 2.5 to 3.4 formulations and the vasopressin pH 3.5 to 4.5 formulations observed in the experiments conducted at 25° C. and 40° C. are shown in FIGS. 17 (25° C.) and 18 (40° C.). The vasopressin assay is presented as a % assay decrease of vasopressin over the four-week study period, rather than absolute assay, because the amount of starting vasopressin varied between the vasopressin pH 2.5 to 3.4 formulations and the vasopressin pH 3.5 to 4.5 formulations.

The results of the above experiments suggested that the stability of a vasopressin formulation was affected by pH. At 25° C., the percent decrease in vasopressin after four weeks was lowest between pH 3.7 and pH 3.8 (FIG. 17). Within the range of pH 3.7 to pH 3.8, the level of impurities was lowest at pH 3.8 (FIG. 15). At 40° C., the percent decrease in vasopressin after four weeks was lowest between pH 3.6 and pH 3.8 (FIG. 18). Within the range of pH 3.6 to pH 3.8, the level of impurities was lowest at pH 3.8 (FIG. 16).

Example 11: Intra-Assay and Inter-Analysis Precision of Vasopressin pH Experiments

The methods used to determine the % assay decrease and amount of impurities in the vasopressin solutions over time in EXAMPLE 10 had both intra-assay and inter-analyst precision.

Intra-assay precision was demonstrated by performing single injections of aliquots of a vasopressin formulation (n=6; Chemist 1) from a common lot of drug product and determining the assay and repeatability (% RSD; relative standard deviation). Inter-analyst precision was demonstrated by two different chemists testing the same lot of drug product; however, the chemists used different instruments, reagents, standard preparations, columns, and worked in different laboratories. The procedure included a common pooling of 20 vials of vasopressin, which were assayed by the two chemists using different HPLC systems and different HPLC columns. The vasopressin assay results (units/mL) and repeatability (% RSD for n=6) were recorded and are reported in the TABLE 44 below.

TABLE 44 Precision of Vasopressin Results. Chemist 1 Chemist 2 Sample (units/mL) (units/mL) 1 19.74 19.65 2 19.76 19.66 3 19.77 19.66 4 19.75 19.72 5 19.97 19.73 6 19.65 19.73 Mean 19.8 19.7 % RSD (≤2.0%) 0.5% 0.2% % Difference = 0.5% (acceptance criteria: ≤3.0%) ${\%\mspace{14mu}{Difference}} = {\frac{\left( {{{Chemist}\mspace{14mu} 1_{Mean}} - {{Chemist}\mspace{14mu} 2_{mean}}} \right)}{\left( {{{Chemist}\mspace{14mu} 1_{Mean}} + {{Chemist}\mspace{14mu} 2_{Mean}}} \right)} \times 200}$

The intra-assay repeatability met the acceptance criteria (% RSD≤2.0%) with values of 0.5% and 0.2%. The inter-analyst repeatability also met the acceptance criteria (% difference≤3.0%) with a difference of 0.5%.

Example 12: Effect of Citrate Versus Acetate Buffer on Vasopressin Formulations

To test the effect of citrate and acetate buffer on vasopressin formulations, a total of twelve solutions of 20 Units/mL vasopressin were prepared in 1 mM citrate buffer, 10 mM citrate buffer, 1 mM acetate buffer, and 10 mM acetate buffer. All of the solutions were prepared in triplicate. Each solution was adjusted to pH 3.5 with hydrochloric acid.

The vasopressin formulations were stored at 60° C. for 7 days, and the assay (% label claim; vasopressin remaining) and % total impurities after 7 days were analyzed by HPLC using the procedure and experimental conditions described in EXAMPLE 1.

The assay (% label claim; vasopressin remaining) and % total impurities for each of the Vasopressin Buffered Formulations are reported in the TABLES 45 and 46 below.

TABLE 45 Assay (% label claim; vasopressin remaining) in the vasopressin formulations after storage at 60° C. for 7 days. Sample Buffer 1 2 3 Average  1 mM citrate buffer 89.5% 89.7% 90.6% 89.9% 10 mM citrate buffer 84.1% 84.4% 84.5% 84.3%  1 mM acetate buffer 90.5% 91.1% 91.9% 91.2% 10 mM acetate buffer 90.9% 90.9% 92.4% 91.4%

TABLE 46 % Total Impurities in the vasopressin formulations after storage at 60° C. for 7 days. Sample Buffer 1 2 3 Average  1 mM citrate buffer 3.4% 3.5% 2.5% 3.1% 10 mM citrate buffer 9.5% 9.0% 9.4% 9.3%  1 mM acetate buffer 3.3% 2.8% 3.2% 3.1% 10 mM acetate buffer 2.9% 2.6% 3.1% 2.9%

The data indicated that the vasopressin assay in the vasopressin formulations with citrate buffer was lower than in the vasopressin formulations with acetate buffer. For example, at 10 mM of either citrate or acetate buffer, the average vasopressin assay was 91.4% in acetate buffer, but was 84.3% in citrate buffer. The data also indicated that % total impurities in the vasopressin formulations with citrate buffer were higher than in the vasopressin formulations with acetate buffer. For example, at 10 mM of either citrate or acetate buffer, the average % total impurities was 2.9% in acetate buffer, but was 9.3% in citrate buffer.

Further, as the citrate buffer concentration increased, the vasopressin assay further decreased (from an average of 89.9% to 84.3%), and the % total impurities increased (from an average of 3.1% to 9.3%). This effect was not observed in the vasopressin formulations with acetate buffer, where the average and % total impurities stayed fairly constant.

Example 15: 15-Month Stability Data for Vasopressin Formulations

The drug product detailed in TABLE 51 was tested for stability over a 15-month period. Three different lots (X, Y, and Z) of the vasopressin drug formulation were stored at 25° C. for 15 months in an upright or inverted position.

The results from TABLES 53-54 indicate that stability of the vasopressin formulations was not significantly affected by either inverted or upright storage. The impurities detected included Gly9 (SEQ ID NO.: 2), Glu4 (SEQ ID NO.: 4), D-Asn (SEQ ID NO.: 10), Asp5 (SEQ ID NO.: 3), Acetyl-AVP (SEQ ID NO.: 7), vasopressin dimer, and several unidentified impurities (UI). The unidentified impurities are labeled with a range of relative retention times at which the impurities eluted from the column.

The results indicate that the pH remained fairly constant over the 15-month period, fluctuating between 3.8 and 3.9 throughout the 15 months. The total impurities did not increase over 5.9%, and the % LC of vasopressin did not decrease below 92%.

FIG. 19 shows a graph depicting the % LC over the 15-month study period for the results provided in TABLES 53-54. The starting amounts of vasopressin were 97.9% LC for lot X, 98.6% LC for lot Y, and 99.3% LC for lot Z. The results indicate that the % LC of vasopressin decreased over the 15-month study period, but did not decrease below 92% LC.

The formula for the trend line of lot X was: % LC=98.6−0.4262(month)

The formula for the trend line of lot Y was: % LC=98.47−0.4326(month)

The formula for the trend line of lot Z was: % LC=99.54−0.3906(month)

Example 17: Impurity Measurement for Vasopressin Formulation for Bottle or Intravenous Drip-Bag

Gradient HPLC was used to determine the concentration of vasopressin and associated impurities in vasopressin formulations similar to those outlined in TABLES 55-63 above. Vasopressin was detected in the eluent using UV absorbance at a short wavelength. The concentration of vasopressin in the sample was determined by the external standard method, where the peak area of vasopressin in sample injections was compared to the peak area of a vasopressin reference standard in a solution of known concentration. The concentrations of related peptide impurities in the sample were also determined using the external standard method, using the vasopressin reference standard peak area and a unit relative response factor. An impurities marker solution was used to determine the relative retention times of identified related peptides at the time of analysis.

The chromatographic conditions used for the analysis are shown in TABLE 64 below:

TABLE 64 Column Phenomenex Kinetex XB-C18, 2.6 μm, 100 Å pore, 4.6 × 150 mm, Part No. 00F-4496-E0 Column 35° C.

Diluent A was 0.25% v/v acetic acid, which was prepared by pipetting 2.5 mL of glacial acetic acid into a 1 L volumetric flask containing 500 mL of water. The volume was diluted with water and mixed well.

Diluent B was prepared by weighing and transferring about 3 g of sodium chloride into a 1 L volumetric flask and then adding 2.5 mL of glacial acetic acid. The solution was diluted to volume with water and mixed well.

Phosphate buffer at pH 3.0 was used for mobile phase A. The buffer was prepared by weighing approximately 15.6 g of sodium phosphate monobasic monohydrate into a beaker. 1000 mL of water was added, and mixed well. The pH was adjusted to 3.0 with phosphoric acid. The buffer was filtered through a 0.45 μm membrane filter under vacuum, and the volume was adjusted as necessary.

An acetonitrile:water (50:50) solution was used for mobile phase B. To prepare mobile phase B, 500 mL of acetonitrile was mixed with 500 mL of water.

The stock standard solution was prepared at 20 units/mL of vasopressin. A solution of vasopressin in diluent was prepared at a concentration of about 20 units/mL. The stock standard solution was prepared by quantitatively transferring the entire contents of 5 vials of USP Vasopressin RS with diluent A to the same 250-mL volumetric flask. The solution was diluted to volume with diluent A and mixed well. 10 mL aliquots of the standard solution was transferred into separate polypropylene tubes. The aliquots were stored at 2-8° C. The stock standard solution was stable for 6 months from the date of preparation when stored in individual polypropylene tubes at 2-8° C.

The working standard solution contained about 0.5 units/mL of vasopressin. Aliquots of the stock standard solution were allowed to warm to room temperature and then mixed well. 2.5 mL of the stock standard solution was transferred into a 100 mL volumetric flask and diluted to volume with Diluent B, and the resultant mixture was denoted as the Working Standard Solution.

The stock standard solution and working standard solution can also be prepared from a single vasopressin vial in the following manner.

One vial of vasopressin with diluent A can be quantitatively transferred to a 50-mL volumetric flask. The solution can be dissolved in and diluted to volume with diluent A and mixed well, and denoted as the stock standard solution. To prepare the working standard solution, 2.5 mL of the stock standard solution was diluted to 100 mL with diluent B and mixed well.

The working standard solution was stable for at least 72 hours when stored in refrigerator or in autosampler vial at 10° C.

The intermediate standard solution was prepared by pipetting 1 mL of the working standard solution into a 50 mL volumetric flask. The solution was diluted to volume with diluent B and mixed well.

The sensitivity solution (0.1% of 0.4 units/mL vasopressin formulation) was prepared by pipetting 2 mL of the intermediate standard solution into a 50 mL volumetric flask. The solution was diluted to the volume with diluent B and mixed well. The sensitivity solution was stable for at least 72 hours when stored in the refrigerator.

To prepare the impurities marker solution, a 0.05% v/v acetic acid solution was prepared by pipetting 200 mL of a 0.25% v/v acetic acid solution into a 1 L volumetric flask. The solution was diluted to the desired volume with water and mixed well.

To prepare the vasopressin impurity stock solutions, the a solution of each impurity as shown below was prepared in a 25 mL volumetric flask and diluted with 0.05% v/v acetic acid to a concentration suitable for HPLC injection.

-   -   Gly-9 AVP: 0.09 mg/mL     -   Glu-4 AVP: 0.08 mg/mL     -   Asp-5 AVP: 0.1 mg/mL     -   D-Asn AVP: 0.08 mg/mL     -   Dimer AVP: 0.07 mg/mL     -   Acetyl AVP: 0.08 mg/mL

To prepare the MAA/H-IBA (Methacrylic Acid/α-Hydroxy-isobutyric acid) stock solution, a stock solution containing approximately 0.3 mg/mL H-IBA and 0.01 mg/mL in 0.05% v/v acetic acid was made in a 50 mL volumetric flask.

To prepare the chlorobutanol diluent, about one gram of hydrous chlorobutanol was added to 500 mL of water. Subsequently, 0.25 mL of acetic acid was added and the solution was stirred to dissolve the chlorobutanol.

To prepare the stock impurity marker solutions, 6.5 mg of vasopressin powder was added to a 500 mL volumetric flask. To the flask, the following quantities of the above stock solutions were added:

-   -   Gly-9 AVP: 20.0 mL     -   Glu-4 AVP: 20.0 mL     -   Asp-5 AVP: 10.0 mL     -   D-Asn AVP: 10.0 mL     -   Dimer AVP: 10.0 mL     -   Acetyl AVP: 20.0 mL     -   H-IBA/MAA: 30.0 mL

The solutions were diluted to volume with the chlorobutanol diluent. The solutions were aliquoted into individual crimp top vials and stored at 2-8° C. The solutions, stored at 2-8° C., were suitable for use as long as the chromatographic peaks could be identified based on comparison to the reference chromatogram.

At time of use the solutions were removed from refrigerated (2-8° C.) storage and allowed to reach room temperature.

The vasopressin stock impurity marker solution was stable for at least 120 hours when stored in autosampler vials at room temperature.

The impurity marker solution were prepared by diluting 1 mL of the stock impurity marker solution to 50 mL with diluent B, and mixed well. The vasopressin impurity marker solution was stable for at least 72 hours when stored in the refrigerator.

To begin the analysis, the HPLC system was allowed to equilibrate for at least 30 minutes using mobile phase B, followed by time 0 min gradient conditions until a stable baseline was achieved.

Diluent B was injected at the beginning of the run, and had no peaks that interfered with vasopressin as shown in FIG. 20.

A single injection of the sensitivity solution was performed, wherein the signal-to-noise ratio of the vasopressin was greater than or equal to ten as shown in FIG. 21.

A single injection of the impurities marker solution was then made. The labeled impurities in the reference chromatogram were identified in the chromatogram of the marker solution based on their elution order and approximate retention times shown in FIG. 22 and FIG. 23. FIG. 23 is a zoomed-in chromatograph of FIG. 22 showing the peaks that eluted between 16 and 28 minutes. The nomenclature, structure, and approximate retention times for individual identified impurities are detailed in TABLE 3.

A single injection of the working standard solution was made to ensure that the tailing factor of the vasopressin peak was less than or equal to about 2.0 as shown in FIG. 24.

A total of five replicate injections of the working standard solution were made to ensure that the relative standard deviation (% RSD) of the five replicate vasopressin peak areas was not more than 2.0%.

Following the steps above done to confirm system suitability, a single injection of the placebo and sample preparations was made. The chromatograms were analyzed to determine the vasopressin and impurity peak areas. The chromatogram for the placebo is depicted in FIG. 25, and the chromatogram for the sample preparation is shown in FIG. 26. Then, the working standard solution was injected after 1 to 10 sample injections, and the average of the bracketing standard peak areas were used in the calculations for vasopressin and impurity amounts. Additional injections of the impurities marker solution could be made to help track any changes in retention time for long chromatographic sequences.

The relative standard deviation (% RSD) of vasopressin peak areas for the six injections of working standard solution was calculated by including the initial five injections from the system suitability steps above and each of the subsequent interspersed working standard solution injections. The calculations were done to ensure that each of the % RSD were not more than 2.0%.

The retention time of the major peak in the chromatogram of the sample preparation corresponded to that of the vasopressin peak in the working standard solution injection that preceded the sample preparation injection.

To calculate the vasopressin units/mL, the following formula was used:

${{Vasopressin}\mspace{14mu}{units}\text{/}{mL}} = {\frac{R_{U}}{R_{S}} \times {Conc}\mspace{14mu}{STD}}$

where:

R_(U)=Vasopressin peak area response of Sample preparation.

R_(S)=average vasopressin peak area response of bracketing standards.

Conc STD=concentration of the vasopressin standard in units/mL

To identify the impurities, the % Impurity and identity for identified impurities (TABLE 3) that are were greater than or equal to 0.10% were reported. Impurities were truncated to 3 decimal places and then rounded to 2 decimal places, unless otherwise specified. The following formula was used:

${\%\mspace{14mu}{impurity}} = {\frac{R_{1}}{R_{s}} \times \frac{{Conc}\mspace{14mu}{STD}}{LC} \times 100\%}$

where R₁=Peak area response for the impurity; LC=label content of vasopressin (units/mL).

The formulations used for the vasopressin and impurity studies are summarized in TABLE 65 below and correspond to several of the formulations detailed above in TABLES 55-63.

The drug products detailed in TABLE 65 were tested for stability over a six month period. The vasopressin drug formulations were stored at 5° C., 25° C., or 40° C. for up to six months. At 0, 1, 2, 3, 4, 5, and 6 months, the amount of vasopressin (AVP), % label claim (LC), amount of various impurities, pH, and % reference standard was measured.
